Euronext's eleventh-device threshold adds €1,490 a month to one derivatives-data licence

A financial institution moving from ten to eleven entitled non-display devices for Euronext's Group Equity and Index Derivatives Level 2 data crosses a published monthly fee threshold from €1,788 to €3,278. That is an increase of €1,490, or 83.3%, for the licence category, before VAT and any qualifying discount. An FXBrokers.ai reconstruction of the fee schedule effective from 1 October 2026 shows why one additional entitlement can matter more to a data budget than several additions within a band. If the higher category applied for twelve months, the difference would be €17,880.[1]

The comparison holds the information product, data depth and customer-use category constant. It is a change between tiers of the same current schedule, not a finding that Euronext raised this customer's bill by 83% in October or that every institution pays the amount quoted. The published rows nevertheless establish a concrete cost mechanism: charges rise in steps, while the eligible device count and permitted activities determine which step applies. A broker assessing a new execution system needs both parts of that calculation.[1]

The steps are uneven

The largest percentage step in this sequence is at the eleventh device. The largest euro step is at the twenty-sixth: moving from the 11–25 band to 26–50 adds €1,639 a month, or €19,668 across twelve months. The sixth-device step adds €447, while moving beyond fifty into the unlimited enterprise category adds €1,043. Counting each additional device at one constant price would therefore produce the wrong estimate. The cost of an expansion depends on the starting position as well as its size.[1]

A worked example makes the distinction clear. Assume an institution qualifies for the standard category, buys only this non-display product at list price and is initially entitled to use ten devices. Increasing to eleven moves the monthly charge to €3,278. Increasing from eleven to twelve leaves it at €3,278. Both changes add one entitlement, but only the first crosses a fee boundary. This is a schedule-based illustration, not a reconstructed invoice from an identified Euronext customer.[1]

The same structure means the average charge per entitled device can move differently from the total bill. At ten devices, €1,788 divided by ten is €178.80. At eleven, €3,278 divided by eleven is €298.00; at twenty-five it is €131.12. Those averages do not change the contractual unit of charging. They show why a business case built only on a per-device average at full utilisation can understate the cost when a small deployment first enters a larger band.[1]

Entitlement determines the band

Euronext defines the relevant count across the market-data client and its affiliates. The schedule refers to aggregated device entitlements to use the product's non-display data at any time in the calendar month. It also says that multiple simultaneously entitled instances under an access ID count separately. This is a broader question than how many people looked at a screen on the final day of the month, and it is not resolved by counting usernames alone.[1]

A system inventory and an entitlement history serve different purposes. An inventory identifies machines, applications and services. The history should establish which of them had the right to use a particular product during the billing period, how simultaneous instances were configured and which affiliates were covered. Removing an obsolete permission may change the evidential count for a later period, but simply observing that a system was quiet does not establish that it was never entitled. The schedule requires auditable records supporting the selected category.[1][4]

That distinction can become material during a platform migration. Old and replacement systems may temporarily coexist, even if the intended permanent architecture is smaller. Whether the overlap crosses a band depends on the actual entitlements and their treatment under the agreement. The public tariff does not reveal any firm's migration pattern, so it cannot establish a realised charge. It does identify the information a procurement team and a technical team must reconcile before agreeing a budget.[1][4]

Nor should the term device be casually replaced with physical server. The explicit rule for multiple instances under an access ID makes software entitlement relevant. Conversely, it would be equally unsafe to assume every installed process is chargeable irrespective of access rights. The defensible comparison is between the contract's defined count and the configuration actually permitted to receive or use the specified data. An invoice review without that mapping cannot confirm that the selected tier is correct.[1]

Redistribution changes another part of the price

A second reconstruction across three adjacent category tables reveals a constant difference. For this product, the redistributing standard financial institution rate is €2,096 a month above the standard rate in every device band. The limited-redistribution rate is €1,048 above it in every band. The corresponding twelve-month differences are €25,152 and €12,576. Thus, the current schedule separates two economic dimensions in a particularly visible way: the device-band progression and the additional price associated with specified redistribution rights.[1]

This is a comparison of listed categories, not evidence that an institution can elect the cheapest label regardless of its activities. The standard category covers internal non-display trading and certain other internal uses. The limited-redistribution category has restricted onward-use conditions; the broader redistributing category allows a wider distribution activity. Operating a trading platform, including internal matching of orders, is outside these standard-institution categories. Other categories address such activities. A firm combining several services must first establish which definition fits.[1][4]

The distinction is particularly relevant to a broker that both routes orders and supplies information to customers. An algorithm can consume data internally while a separate service distributes prices or derived outputs. Treating the whole business as one screen subscription can miss those different rights. Equally, the existence of a customer website alone does not prove that the broadest redistribution category applies: the actual content, contractual arrangement and permitted recipients need to be examined.[1][4]

The €2,096 and €1,048 differences are specific to the Level 2 equity-and-index derivatives product tested. They should not be carried across to every Euronext market, depth or use class. The full schedule contains other products and price structures. Even within the tested product, separate display charges may apply, and the schedule excludes connectivity services. The reconstructed tariff component is therefore one part of a total data bill, not an estimate of the entire cost of operating a brokerage platform.[1]

Discounts and the transition qualify the result

The schedule includes a 25% reduction that qualifying standard-category derivatives market makers may apply for. Its cumulative conditions include an applicable market-maker agreement or scheme, positive market-making volume and trading solely for the firm's own account without broker or agency activity. Those conditions are consequential for this readership: a brokerage cannot assume that a discount available to a qualifying proprietary market maker applies to its agency business. The headline comparison deliberately uses undiscounted list fees.[1]

If an eligible institution received that 25% reduction on both adjacent bands, the ten-to-eleven-device difference would be €1,117.50 a month, rather than €1,490. The percentage increase between those two discounted fees would still be 83.3%. This sensitivity does not establish eligibility or an actual award. It shows that a uniform percentage discount changes the euro size of a threshold without removing the underlying step structure.[1]

Euronext places the new commercial model within the EU's reasonable-commercial-basis framework. Its published explanation describes pricing linked to costs and a reasonable margin. That policy rationale is relevant context, but it does not establish that every customer's total bill must fall. Nor does the existence of a steep tier boundary by itself establish discriminatory or unlawful pricing. Testing compliance would require the applicable rules, cost methodology and facts of the relevant customer category, beyond the arithmetic presented here.[2]

The transition guidance also distinguishes contractual routes. Some customers have provider-administered updates; others need a new order form. Certain distribution, derived-data and index activities previously handled under the Euronext Datafeed Subscriber Agreement require an Euronext Market Data Agreement. These distinctions matter because the price row must be read with the rights it purchases. Signing an updated form without reconciling its category to the system and business-use map leaves the central charging question unanswered.[2][3]

What a comparable invoice test would require

A before-and-after claim about October requires another layer of work. The old and new invoices must be normalised for product content, permissions, device count, affiliated entities, discounts, taxes and third-party services. A renamed bundle or expanded right can make two superficially similar rows non-comparable. This review establishes the structure of the October schedule rather than substituting a current-tier comparison for that missing historical invoice evidence.[1][3]

For a firm planning its next deployment, however, the current arithmetic is already actionable. The tested eleventh-device threshold adds €1,490 at list price; the twenty-sixth adds €1,639. Redistribution classification adds a separate, fixed difference across these bands. The next evidential question is how those boundaries interact with real customers' entitlements and contractual rights. That can be tested with records without assuming either that the reform reduced every bill or that a published threshold demonstrates customer harm.[1]
